The Aberdeen defender has been one of the stand-outs of the season so far, but will be in competition with Serie A star Hickey, who can play on either side and struck his first goal for Bologna this week, and is seeking a first cap at under-21 level. Easter Road youngster Doig missed out on his first call-up in May following his break-out season but made the cut against Turkey last month.
How, and if, Gemmill fits all three in will be a dilemma not dissimilar to that which national boss Steve Clarke has had to develop with left-backs Andy Robertson and Kieran Tierney at senior level.
Also in the mix for the match at Tynecastle are Celtic duo Adam Montgomery and Stephen Welsh who have both been heavily involved in Ange Postecoglou’s first-team since the Australian took over at Parkhead, and Manchester City pair Lewis Fiorini and Cieran Slicker.
Rangers have five players in the squad; Stephen Kelly plus the loaned out quartet of Ben Williamson, Kai Kennedy, Glenn Middleton and Lewis Mayo, plus the Auchenhowie trained Dapo Mebude and Brian Kinnear who both left the Glasgow club over the summer.
In total, nine of the squad selected by Scot Gemmill come from the SFA’s Performance school programme, and the squad also includes on-loan Hibs forward James Scott and ten players based south of the border.
The match is scheduled for Hearts’ home ground on October 7 with a 7.05pm kick off and shown live on BBC Scotland having been switched from Scandinavia at Denmark’s request.
